IBM工作灯OutOfSyncException

Question

环境：

1. IBM工作灯6.2.0.0消费版
2. 自由8.5.5.1
3. IBM DB2
4. 的Windows 2008服务器
5. iPhone 5 - 7 IOS
6. 基于适配器的认证

Worklight Server的2个节点指向一个DB2实例。

当我尝试登录时，会经常提示直接更新。但我有一个更新的版本在我的设备上运行。

即使我继续进行更新，设备构建也会回滚到之前的构建。

设备提示更新后，此时新版本已更新。

我得到以下为日志。

这是因为两个Worklight实例指向相同的DB2？我认为情况并非如此。

帮我解决回滚构建问题。

Answer 1

这可能会发生，因为您使用两个独立的Libery配置文件应用程序服务器，它们都指向同一个数据库。

因为它们是独立的，所以在发生直接更新时它们不会“同步”。
要启用此同步，应用程序服务器必须部署为服务器场。

有关服务器场的更多信息，请查看以下文档主题：Defining a server farm for Worklight Server administration
